Production process characteristics
High purity melting technology
Vacuum melting: Vacuum induction melting (VIM) or electron beam melting (EBM) is used, with nickel content ≥ 99.9% (N4 grade) or ≥ 99.5% (N6 grade), total impurities ≤ 0.05%, oxygen content ≤ 10ppm, to ensure material purity from the source.
Precision casting: The ingot is hot-rolled/forged to a diameter of 6-12mm wire rod, with grain size controlled at ASTM 4-5 levels, laying the foundation for subsequent wire drawing.
Ultra fine drawing process and surface finishing treatment
Gradual diameter reduction: Multi pass cold drawing (single deformation ≤ 15%), combined with diamond molds and emulsion lubrication, with a diameter range covering 0.015-10mm and a tolerance of ± 0.005mm (military grade).
Intermediate annealing: After each processing, it is annealed under hydrogen protection at 650-850 ℃ to eliminate work hardening and maintain an elongation rate of ≥ 25%.
Electrolytic polishing: treated in a mixture of H ₂ SO ₄ - H ∝ PO ₄, with a surface roughness Ra ≤ 0.2 μ m, to enhance conductivity and corrosion resistance.
Clean packaging: Class 100 cleanroom roll up, vacuum anti-static packaging to avoid micro particles.
application area
New Energy and Electricity
Battery ear/current collector: N4 nickel wire (diameter 0.05-0.5mm) is used for welding lithium battery ear, reducing internal resistance by more than 7%;
Hydrogen equipment: N6 nickel wire woven mesh is used as an electrode for hydrogen production through electrolysis of water, with a lifespan
exceeding 15000 hours.
Precision electronic manufacturing
Semiconductor bonding wire: N6 ultra-fine wire (diameter 0.025mm ± 0.002mm) is connected to the chip pins, and the number of thermal fatigue cycles is 3.2 times that of traditional materials;
Electric vacuum device: High purity nickel wire (N4) is used for the grid of vacuum tubes, which is resistant to electron bombardment and has a low
gas release rate.
High temperature and anti-corrosion system
Thermocouple sheath: K/N type thermocouple sheath made of N4 wire material, capable of withstanding high temperature corrosion at 1100 ℃;
Chemical filter mesh: N6 nickel wire woven mesh is used for strong alkali reaction vessels, with a lifespan 5 times longer than stainless steel.
Medical and cutting-edge technology
Orthodontic archwire: Nickel titanium alloy wire provides continuous orthodontic force, with biocompatibility certified by ISO 5832-4;
Aerospace sensor: A 0.10mm nickel wire (N6) is used for engine temperature monitoring, maintaining signal stability under temperature differences of -200~500 ℃.
As the "micro scale network" of modern industry, the technical value and application breadth of nickel wire are continuously expanding with the progress of materials science. This seemingly simple metal wire is actually an invisible bridge connecting basic materials with cutting-edge technology.
